In 1948 Britain declared an Emergency in Malaya

It wasn't really an emergency. It was a guerrilla war.

And Britain would spend 12 years trying to drive communists out of its territory. What were we doing there?

Ros Taylor talks to Open University history professor Karl Hack and Economist bureau chief Dominic Ziegler about what the UK did in Malaya, and why Singapore cultivates positive memories of British occupation.

'Oh, bugger orf!' We all know Received Pronunciation when we hear it. But what makes this accent distinctive? Why do people still pay to learn how to speak RP – and does it really bring the advantages it used to?

Ros Taylor talks to voice coach and actor Alix Dunmore and Professor of Phonetics Jane Setter about how to spot an RP speaker – and how the accent has changed over the past century.

Speeches by Lord Brabazon of Tara and Lord Wedgwood are taken from a Lords debate in 1943 and are voiced by historian Seth Thévoz.

No one dies of diphtheria or polio in Britain any more. Since World War Two, we've virtually wiped out the diseases that used to kill tens of thousands of children every year. But rolling out a vaccine isn't always easy.

Ros Taylor talks to public health historian Gareth Millward and Stuart Blume, the author of Immunisation, about jabs and why some people refuse them.
